first embodiment
[0035]A first embodiment according to the present disclosure will hereinafter be described.
[0036]FIG. 1 is an external view showing a schematic configuration of an image scanner 10 according to the present embodiment. FIG. 2 is a side cross-sectional view showing an outline of a conveying section of the image scanner 10. It should be noted that FIG. 2 is a side cross-sectional view in the case of viewing the image scanner 10 from the X direction perpendicular to the conveying direction (a Y direction).
Schematic Configuration of Image Scanner 10
[0037]As shown in FIG. 1, the image scanner 10 according to the present embodiment is provided with a device main body (hereinafter abbreviated as a main body 11), and a form support 12 on which a form P (see FIG. 2) as an object is mounted. Inside the main body 11, there are disposed the conveying section 13 for conveying the form P, a scanning section 14 for reading an image of the form P thus conveyed, an ultrasonic sensor 15 (an overlap fe...
second embodiment
[0133]Then, a second embodiment according to the present disclosure will be described.
[0134]In the first embodiment, the transmission section 151 is provided with the plurality of transmission columns 23A disposed along the Y direction, and performs the beam focusing defining the center of the first aperture part 153A as the focal point F by performing the delayed drive on the transmission columns 23A. In contrast, the second embodiment is different from the first embodiment described above in the point of individually driving each of the transmission elements 23 arranged in a two-dimensional array structure in the X direction and the Y direction to thereby perform the beam focusing. It should be noted that in the following description, the matters having already been described are denoted by the same reference symbols, and the description thereof will be omitted or simplified.
[0135]FIG. 10 is a schematic plan view showing an arrangement configuration example of the transmission ele...
modified examples
[0147]It should be noted that the present disclosure is not limited to each of the embodiments described above, but includes modifications and improvements within a range where the advantages of the present disclosure can be achieved, and configurations, which can be obtained by, for example, arbitrarily combining the embodiments.
